Equipment Checklist for AASHTO M 205
Molds for Forming Concrete Test Cylinders
 
All equipment shall be inspected for compliance with appropriate dimensions, as stated in each standard, as well as to determine if it is in satisfactory operating condition (i.e.; adherence of mortar, deformed molds, etc.). Inspection shall occur at least annually, or whenever there is reason to suspect nonconformance with the standard.
